The Earlier the Better: Surgical Stabilization of Rib Fractures Associated With Improved Outcomes.

INTRODUCTION: Surgical stabilization of rib fractures (SSRF) has been associated with lower rates of mortality and fewer respiratory complications. This study sought to evaluate the association between SSRF timing and patient outcomes. METHODS: This retrospective analysis included patients aged ≥45 y who underwent SSRF in the Trauma Quality Improvement Program database from 2016 to 2020. Primary outcome was incidence of ventilator-assisted pneumonia (VAP). Secondary outcomes included acute respiratory distress syndrome (ARDS), unplanned endotracheal intubation, in-hospital mortality, failure to rescue (FTR) after all major complications, and FTR after severe respiratory complications. Logistic regression models of outcomes on timing to SSRF were fit while controlling for age, gender, body mass index, injury severity score, flail chest, chronic obstructive pulmonary disease, congestive heart failure, and smoking. RESULTS: Among 4667 patients who received SSRF, average time to SSRF was 4.6 ± 3.2 d. Each additional day to SSRF was associated with increased odds of VAP (odds ratio [OR] 1.07, confidence interval [CI] 1.03-1.11) and intubation (OR 1.10, CI 1.08-1.13). A longer time to SSRF was associated with increased odds of ARDS (OR 1.10, CI 1.05-1.15), while no significant association was observed for in-hospital mortality (OR 0.99, CI 0.93-1.04). A longer time to SSRF was associated with decreased odds of FTR after a major complication (OR 0.90, CI 0.83-0.97) and respiratory complications (OR 0.87, CI 0.78-0.96). CONCLUSIONS: For each day that SSRF is delayed, increased odds of VAP, intubation, and ARDS were observed. Prompt intervention is crucial for preventing these complications and improving our ability to rescue patients.

Outcomes after fixation of rib fractures sustained during cardiopulmonary resuscitation: A retrospective single center analysis.

Background: Historically rib fractures have been typically treated non-operatively. Recent studies showed promising results after osteosynthesis of rib fractures in trauma patients with flail segments or multiple rib fractures. However, there is a paucity of data on rib fixation after cardiopulmonary resuscitation (CPR). This study evaluated the outcomes of patients who received rib fixation after CPR. Methods: Adult patients who received surgical fixation of rib fractures sustained during CPR between 2010 and 2020 were eligible for inclusion in this retrospective study. Outcome measures included complications, quality of life (EQ 5D 5L) and level of dyspnea. Results: Nineteen patients were included with a mean age of 66.8 years. The mean number of fractured ribs was ten, seven patients additionally had a sternum fracture. Pneumonia occurred in 15 patients (74%), of which 13 were diagnosed preoperatively and 2 post-operatively. Six patients developed a postoperative pneumothorax, none of which required revision surgery. One patient showed persistent flail chest after rib fixation and required additional fixation of a concomitant sternum fracture. One infection of the surgical site of sternal plate occurred, while no further surgery related complications were reported. Mean EQ-5D-5L was 0.908 and the average EQ VAS was 80. One patient reported persisting dyspnea. Conclusion: To date, this is the largest reported cohort of patients who received rib fixation for fractures sustained during CPR. No complications associated with rib fixation were reported whereas one infection after sternal fixation did occur. Current follow-up demonstrated a good long-term quality of life after fixation, warranting further studies on this topic. Deeper knowledge on this subject would be beneficial for a wide spectrum of physicians.

Effect of surgical stabilization of rib fractures in polytrauma: an analysis of the TraumaRegister DGU®.

PURPOSE: In severely injured patients with multiple rib fractures the beneficial effect of surgical stabilization is still unknown. The existing literature shows divergent results and especially the indication and the right timing of an operation are subject of a broad discussion. The aim of this study was to determine the influence of a surgical stabilization of rib fractures (SSRF) on the outcome in a multi-center database with special regard to the duration of ventilation, intensive care and overall hospital stay. METHODS: Data from the TraumaRegister DGU® collected between 2008 and 2017 were used to evaluate patients over 16 years with severe rib fractures (AIS ≥ 3). In addition to the basic comparison a matched pair analysis of 395 pairs was carried out in order to find differences and to increase comparability. RESULTS: In total 483 patients received an operative treatment and 29,447 were treated conservatively. SSRF was associated with a significantly lower mortality rate (7.6% vs. 3.3%, p = 0.008) but a longer ventilation time and longer stay as well as in the intensive care unit (ICU) as the overall hospital stay. Both matched pair groups showed a good or very good neurological outcome according to the Glasgow Outcome Scale (GOS) in 4 of 5 cases. Contrary to the existing recommendations most of the patients were not operated within 48 h. CONCLUSIONS: In our data set, obviously most of the patients were not treated according to the recent literature and showed a delay in the time for operative care of well over 48 h. This may lead to an increased rate of complications and a longer stay at the ICU and the hospital in general. Despite of these findings patients with operative treatment show a significant lower mortality rate.

Impact of Time of Surgery on the Outcome after Surgical Stabilization of Rib Fractures in Severely Injured Patients with Severe Chest Trauma-A Matched-Pairs Analysis of the German Trauma Registry.

Purpose: In severely injured patients with multiple rib fractures, the beneficial effect of surgical stabilization is still unknown. The existing literature shows divergent results, and the indication and especially the right timing of an operation are the subject of a broad discussion. The aim of this study was to determine the influence of the time point of surgical stabilization of rib fractures (SSRF) on the outcome in a multicenter database with special regard to the duration of ventilation, intensive care, and overall hospital stay. Methods: Data from the TraumaRegister DGU collected between 2010 and 2019 were used to evaluate patients above 16 years of age with severe rib fractures [Abbreviated Injury Score (AIS) ≥ 3] who received an SSRF in a matched-pairs analysis. In this matched-pairs analysis, we compared the effects of an early SSRF within 48 h after initial trauma vs. late SSRF 3-10 days after trauma. Results: After the selection process, we were able to find 142 matched pairs for further evaluation. Early SSRF was associated with a significantly shorter length of stay in the intensive care unit (16.2 days vs. 12.7 days, p = 0.020), and the overall hospital stay (28.5 days vs. 23.4 days, p = 0.005) was significantly longer in the group with late SSRF. Concerning the days on mechanical ventilation, we were able to demonstrate a trend for an approximately 1.5 day shorter ventilation time for patients after early SSRF, although this difference was not statistically significant (p = 0.226). Conclusions: We were able to determine the significant beneficial effects of early SSRF resulting in a shorter intensive care unit stay and a shorter length of stay in hospital and additionally a trend to a shorter time on mechanical ventilation.

Operative versus non-operative management of rib fractures in flail chest after cardiopulmonary resuscitation manoeuvres.

OBJECTIVES: Blunt chest trauma after mechanical resuscitation manoeuvres appears to have a significant impact on the often complicated course. Due to a lack of data in the literature, the purpose of this study was to investigate the feasibility and immediate outcome of chest wall stabilization for flail chest in this vulnerable patient population. METHODS: We retrospectively reviewed the medical records of patients after cardiopulmonary resuscitation between January 2014 and December 2018 who were diagnosed with flail chest. We attempted to compare patients after surgery with those after conservative treatment. RESULTS: Of a total of 56 patients with blunt chest trauma after mechanical resuscitation and after coronary angiography, 25 were diagnosed with flail chest. After the exclusion of 2 patients because of an initial decision to palliate, 13 patients after surgical stabilization could be compared with 10 patients after conservative therapy. Although there was no significant difference in the total duration of ventilatory support, there was a significant advantage when the time after stabilization to extubation was compared with the duration of ventilation in the conservative group. The presence of pulmonary contusion, poor Glasgow Coma Scale score or the development of pneumonia negatively affected the outcome, but additional sternal fracture did not. CONCLUSIONS: Surgical stabilization for chest wall instability is well tolerated even by this vulnerable patient population. Our results should be used for further randomized controlled approaches. It is necessary to evaluate the situation with all parameters in an interdisciplinary manner and to decide on a possible surgical therapy at an early stage if possible.

Chest Compression-Related Flail Chest Is Associated with Prolonged Ventilator Weaning in Cardiac Arrest Survivors.

Chest compressions during cardiopulmonary resuscitation (CPR) may be associated with iatrogenic chest wall injuries. The extent to which these CPR-associated chest wall injuries contribute to a delay in the respiratory recovery of cardiac arrest survivors has not been sufficiently explored. In a single-center retrospective cohort study, surviving intensive care unit (ICU) patients, who had undergone CPR due to medical reasons between 1 January 2018 and 30 June 2019, were analyzed regarding CPR-associated chest wall injuries, detected by chest radiography and computed tomography. Among 109 included patients, 38 (34.8%) presented with chest wall injuries, including 10 (9.2%) with flail chest. The multivariable logistic regression analysis identified flail chest to be independently associated with the need for tracheostomy (OR 15.5; 95% CI 2.77−86.27; p = 0.002). The linear regression analysis identified pneumonia (ß 11.34; 95% CI 6.70−15.99; p < 0.001) and the presence of rib fractures (ß 5.97; 95% CI 1.01−10.93; p = 0.019) to be associated with an increase in the length of ICU stay, whereas flail chest (ß 10.45; 95% CI 3.57−17.33; p = 0.003) and pneumonia (ß 6.12; 95% CI 0.94−11.31; p = 0.021) were associated with a prolonged duration of mechanical ventilation. Four patients with flail chest underwent surgical rib stabilization and were successfully weaned from the ventilator. The results of this study suggest that CPR-associated chest wall injuries, flail chest in particular, may impair the respiratory recovery of cardiac arrest survivors in the ICU. A multidisciplinary assessment may help to identify patients who could benefit from a surgical treatment approach.

Is it Necessary to Stabilize Every Fracture in Patients with Serial Rib Fractures in Blunt Force Trauma?

Introduction: Management of traumatic rib fractures is subject of controversial discussions. Rib fractures are common, especially after traffic accidents and falls. There is no consensus on whether and how many rib fractures need reconstruction. Not every rib fracture needs to be stabilized, but conservative treatment by internal splinting and analgesia is not effective for all patients. Deformities of the chest wall with reduced thoracic volume and restrictive ventilation disorders must be avoided. Intraoperative assessment of fractures and chest stability plays a central role. Material and methods: From 07/2016 to 07/2021, a total of 121 chest wall stabilizations were performed (m:f = 2:1, age 65 ± 14.5 a). Indications for surgery were the following criteria: (1) palpatory instability of the chest wall, (2) dislocated fracture endings, (3) concomitant injuries, (4) uncontrollable pain symptoms. In all patients, a computed tomography scan of the thorax was performed before the osteosynthetic treatment to assess dislocation of the fracture endings and possible concomitant injuries of intrathoracic organs. Results: Video-assisted thoracoscopy was performed in all patients. Hemothorax and concomitant injuries of the lung, diaphragm and mediastinum could be assessed. This was followed by an intraoperative assessment of the rib fractures, in particular penetration of fracture endings and resulting instability and deformity. Relevant fractures could be identified and subsequent incisions for rib osteosynthesis precisely defined. 6.3 (±2.7) rib fractures were detected, but 2.4 (±1.2) ribs treated osteosynthetically. Bilateral rib fractures were present in 26 patients (21.5%). Post-operative bleeding occurred in seven patients (5.8%), a breakage of the osteosynthetic material in two patients (1.7%). Discussion: Intraoperative assessment of relevant fractures and dislocation is the decisive criterium for osteosynthesis. Thoracoscopy is mandatory for this purpose - also to identify accompanying injuries. Not every fracture has to be approached osteosynthetically. Even with serial rib fractures or multiple fractures in a single rib, the thoracic contour can be restored by stabilizing only relevant fractures. Intraoperative palpation can adequately assess the stability and thus the result of the osteosynthesis. Even after surgical treatment of thoracic trauma, adequate analgesia and respiratory therapy are important to the healing process.

Surgical stabilization of serial rib fractures is advantageous in patients with relevant traumatic brain injury.

PURPOSE: To evaluate the clinical benefit of surgical stabilization of rib fractures (SSRF) in polytrauma patients with serial rib fractures. METHODS: Retrospective single-center cohort analysis in trauma patients. Serial rib fracture was defined as three consecutive ribs confirmed by chest computer tomography (CT). Study cohort includes 243 patients that were treated conservatively and 34 patients that underwent SSRF. Demographic patient data, trauma mechanism, injury pattern, Injury Severity Score (ISS), Glasgow Coma Scale (GCS) and hospital course were analyzed. Two matched pair analyses stratified for ISS (32 pairs) and GCS (25 pairs) were performed. RESULTS: The majority of patients was male (74%) and aged 55 ± 20 years. Serial rib fractures were associated with more than 6 broken ribs in average (6.3 ± 3.7). Other thoracic bone injury included sternum (18%), scapula (16%) and clavicula (13%). Visceral injury consisted of pneumothorax (51%), lung contusion (33%) and diaphragmatic rupture (2%). Average ISS was 22 ± 7.3. Overall hospital stay was 15.9 and ICU stay 7.4 days. In hospital, mortality was 13%. SSRF did not improve hospital course or postoperative complications in the complete study cohort. However, patients with a significantly reduced GCS (7.6 ± 5.3 vs 11.22 ± 4.8; p = 0.006) benefitted from SSRF. Matched pair analysis stratified for GCS showed shorter ICU stays (9 vs 15 days; p = 0.005) including shorter respirator time (143 vs 305 h; p = 0.003). CONCLUSION: Patients with serial rib fractures and simultaneous moderate or severe traumatic brain injury benefit from surgical stabilization of rib fractures.

3D printed modeling contributes to reconstruction of complex chest wall instability.

BACKGROUND: Three-dimensional printed models are increasingly used in many fields including medicine and surgery, but their use in the planning and execution of complex chest wall reconstruction has not been adequately described. In cases of non-union or prior attempts at chest wall reconstruction which have failed, there can be substantial deviations from expected chest wall anatomy. We report a novel technique for pre-operative planning and surgical execution of complex chest wall reconstruction, assisted by 3D printing. Our objective was to utilize 3-D volumetric modeling coupled with 3-D printing to produce patient-specific models for chest wall reconstruction in complex cases. METHODS: Soft tissue reconstruction 0.75 mm slice thickness computed tomography (CT) imaging data was loaded into medical CAD software for segmentation. Lung, muscle, foreign bodies, and bony structureswere separated due to the differences in density between them. The 3D volumetric mesh was then quality checked and stereolithography files (STL) were made which were able to be utilized by the 3D printer. The STL files were exported to a Objet 500 material jetting printer that utilized several UV light cured photopolymers. RESULTS: As an example case, we discuss a 55 year old male who underwent resuscitative thoracotomy. In the early post-operative period, he developed a pulmonary hernia in the 6th intercostal space, repaired with wire cerclage reapproximation of ribs. He developed a symptomatic mobile chest wall at the site of prior repair with additional concern for dissociated anterior cartilage. In preparation for operative repair, a 3D printed model was created, demonstrating fractured cartilage anteriorly as well a saw effect through the six and seventh ribs. An additional model was created using the normal ribs from the right side in mirror image reflection to quantify the degree and precise geometry of mal-alignment to the left chest. These models were then utilized to determine the operative approach via a thoracotomy incision to remove the cerclage wires, followed by parasternal incision, reduction and plating of the sternocostal non-union bursa Rib non-unions were plate stabilized. Repeat imaging in follow-up has demonstrated continued appropriate alignment and the patient reported improvement in his symptoms. CONCLUSION: At present, the cost of 3-D printing remains substantial, but given the improved planning in complex cases, this cost may be recaptured in the reduction of operative time and improved outcomes with reduced re-operation rates. We believe that the early adoption of this technology by surgeons can help improve surgical quality and provide enhanced individualized patient care. These patient-specific models facilitate identification of features which are often not detected with standard 3-D reconstructed CT rendering. Centers should pursue the integration of 3-D printed models into their practice and active collaborations between surgeons and modeling experts should be sought at every available opportunity.

An unexpected fracture of a titanium rib plate in a patient with traumatic brain injury.

Surgical stabilization of rib fractures has been accepted and successfully performed for the management of patients with multiple rib fractures. Several types of devices, such as titanium bar, plate, and screws, are used for rib stabilization. Titanium devices provide a strong support for rib fixation and chest wall reconstruction and are rarely associated with complications. Herein, we report an unusual case of mechanical failure associated with a broken titanium plate. A 47-year-old man was treated with surgical stabilization of rib fractures using titanium plates after blunt trauma leading to epidural hematoma and massive hemothorax. After decompressive craniectomy, bleeding control, and rib fixation for chest trauma, he developed hyperactive delirium, which was not well controlled. On the 17 day of operation, a chest radiograph showed a broken rib plate. Surgeons who perform surgical rib stabilization should be aware that titanium plates are vulnerable to breakage under some conditions, such as hyperactive delirium.

Blunt chest trauma: is there a place for rib stabilization?

Rib fractures are a common and highly morbid finding in patients with blunt chest trauma. Over the past decade, a renewed interest in (and instrumentation for) rib fixation in this cohort has occurred. Stabilization of the chest wall in this setting, particularly when a flail segment is present, is associated with significant reductions in the rates of respiratory failure, pneumonia, ICU stay, and mortality. Thoracic surgeons should remain actively involved in this evolving area of our specialty to further optimize patient outcomes.

Surgical stabilization of flail chest: the impact on postoperative pulmonary function.

OBJECTIVES: Flail chest results in significant morbidity. Controversies continue regarding the optimal management of flail chest. No clear guidelines exist for surgical stabilization. Our aim was to examine the association of bedside spirometry values with operative stabilization of flail chest. METHODS: IRB approval was obtained to identify patients with flail chest who underwent surgical stabilization between August 2009 and May 2011. At our institution, all rib fracture patients underwent routine measurement of their forced vital capacity (FVC) using bedside spirometry. Formal pulmonary function tests were also obtained postoperatively and at three months in patients undergoing stabilization. Both the Synthes and Acute Innovations plating systems were utilized. Data is presented as median (range) or (percentage). RESULTS: Twenty patients (13 male: 65 %) with median age of 60 years (30-83) had a median of four ribs (2-9) in the flail segment. The median Injury Severity Score was 17 (9-41) and the median Trauma and Injury Severity Score was 0.96 (0.04-0.99). Preoperative pneumonia was identified in four patients (20 %) and intubation was required in seven (35 %). Median time from injury to stabilization was four days (1-33). The median number of plates inserted was five (3-11). Postoperative median FVC (1.8 L, range 1.3-4 L) improved significantly as compared to preoperative median value (1 L, range 0.5-2.1 L) (p = 0.003). This improvement continued during the follow-up period at three months (0.9 L, range 0.1-3.0) (p = 0.006). There were three deaths (15 %), none of which were related to the procedure. Subsequent tracheostomy was required in three patients (15 %). The mean hospital stay and ventilator days after stabilization were nine days and three days, respectively. Mean follow-up was 5.6 ± 4.6 months. CONCLUSION: Operative stabilization of flail chest improved pulmonary function compared with preoperative results. This improvement was sustained at three months follow-up.

Rib stabilization: lessons learned.

INTRODUCTION: The management of rib fractures and flail chest has changed considerably over the past century, and recently there has been a renewed interest in operative rib stabilization for these injuries. Despite numerous reports suggesting improved outcomes with rib stabilization, there are not well-defined indications and the approach remains somewhat controversial. MATERIALS AND METHODS: The authors reflect on their experience of performing rib stabilization in over 100 patients with rib fractures and flail chest. CONCLUSION: The authors offer their opinions on this operation with respect to rationale, indications, timing, technique, and postoperative care.
